Weather in September
Temperature
Coson sees its peak of temperatures during August and September, with an average high-temperature of 29.3°C (84.7°F).Heat index
Throughout September, the heat index is appraised at a sweltering 36°C (96.8°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Resist overexposure. Safeguarding from solar damage is indispensable. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
